MET Laboratories has years of experience to assure our customers that the evaluation reflects the electrical attenuation performance of the material. Often times, our test report becomes supporting documentation for our customer’s end-user contractual requirement, where Independent Test Laboratory results verify the electrical performance of the material being tested.

MET Laboratories can use standardized SE test methods, or use standards such as IEEE-299 or ASTM E 1851 or MIL-STD-285 as procedural guides to the evaluation.

MET also tests shielding effectiveness to these military standards:

MIL-DTL-83526

MIL-PRF-28876

MIL-PRF-85045

MET’s testing of the electromagnetic shielding effectiveness of planar material to ASTM test method D4935-1 has benefitted from the pictured test fixture. Dynamic range of greater than 80dB is achievable.
